The proper method for calculating hatch rates:
Number of eggs placed in incubator: (X)
Divide the number of eggs that hatch (Y) by (X)
This will give you a basic starting rate (N)
Then you have to make adjustments for information gathering errors.
To use these adjustments you multiply N by the adjustment percentage.
Shipped eggs adjustment................. 1.64
Eggs that have been transported by motor vehicle 1.25
Eggs containing DNA for webbed feet .002
Eggs containing DNA for flat bills .32
Turkey eggs 1.34
Show bird eggs (non-webbed) 1.57
Show bird eggs (webbed) .1
Using a foam incubator 2.3
Incubators in States starting with a M 1.75
VWN wilderness area 0.4
South of the Mason-Dixon line 0.93
After making these adjustments you will get the actual hatch rate....
As a bonus after you announce these rates you will be qualified to be a Global warming proponent.
These are true and tested to be accurate by the majority of professional hatchers in this area.
